There are no newer-gen Pokémon just yet. Of course, I do still plan on creating an 'expanded PokéDex version' of the game at some point, where there will be a certain selection of them.

For now the only form changes I'm going for is Deoxys' Speed and Normal forms, but if I can properly expand the Dex (keeping save file compatibility) I'd like its other forms too. If not, I'd just like to be able to switch the two mentioned forms in-game somehow. I know there is a method to permanently switch between them (by hard-coding it into the ROM), but it would be really cool to do it without expanding the Dex. I suppose an ASM routine would be able to do this, but I am no expert on ASM right now. If anyone can put together something like this (speed/normal form temporary change in-game) and share it, that would be epic.

I'll check out the links you gave, and I will be visiting the Discord more often soon. Unfortunately I've got college finals this week but after that I will be working on all of this a lot more.
